Trace anomaly and interior curvature of neutron stars in energy-momentum squared gravity
Ratikanta Swain, Sayantan Ghosh, Bharat Kumar
In energy-momentum squared gravity (EMSG), the spacetime inside a neutron star is sourced by effective thermodynamic variables that need not coincide with the physical fluid pressu…

Observable Signatures of a Quarkyonic Phase in Neutron Stars
Probit J Kalita, Tuhin Malik, Tianqi Zhao +2
Quarkyonic matter in \(β\)-equilibrium is a potential description of cold dense matter in neutron stars (NSs), that introduces non-interacting quarks alongside nucleons and lepton…

Spacetime Curvature as a Probe of Exotic Core Phases in Neutron Stars within Modified Gravity
Sayantan Ghosh, Bharat Kumar, Subhash Mahapatra
In this study, we investigate the effect of Energy-Momentum Squared Gravity (EMSG) on the curvature of neutron stars (NSs) by using three relativistic mean-field (RMF) equations of…
